Remove the alignment plate and remount the receiver optics housing. Tighten the quick
coupling firmly. Remove the detector card and replace it with the cross-hair.
Align the receiver with the two hexagonal socket screws, by tightening and loosening them until
the light-dot is centered on the cross-hair.
Note
The stability of the optics housing alignment depends on the stability of the construction to
which the customer's flange is mounted. If the incinerator wall or smoke duct is subject to
movements due to, for instance, thermal changes, LDS6, Optics Housing CD 6 will need
repeated realignment. This can be avoided by mounting the optics housing pair on an external,
more stable base, like a concrete or steel support.
